Future Key Issue
Potential
environmental impacts arising from the above upcoming construction activities in
the next reporting month of November 2019 are mainly associated with dust,
marine water quality, marine ecology and waste management issues.
According to the findings of
the Northwest New Territories (NWNT) Traffic and Infrastructure Review
conducted by the Transport Department, Tuen Mun Road, Ting Kau Bridge, Lantau
Link and North Lantau Highway would be operating beyond capacity after 2016.
This forecast has been based on the estimated
increase in cross boundary traffic, developments in the Northwest New
Territories (NWNT), and possible developments in North Lantau, including the
Airport developments, the Lantau Logistics Park (LLP) and the Hong Kong –
Zhuhai – Macao Bridge (HZMB). In order to cope with the anticipated
traffic demand, two new road sections between NWNT and North Lantau – Tuen Mun – Chek
Lap Kok Link (TM-CLKL) and Tuen
Mun Western Bypass (TMWB) are
proposed.
An Environmental Impact Assessment
(EIA) of TM-CLKL (the Project) was prepared in accordance with the EIA Study
Brief (No. ESB-175/2007) and the Technical Memorandum of the Environmental
Impact Assessment Process (EIAO-TM). The EIA Report was submitted under the Environmental Impact Assessment
Ordinance (EIAO) in August 2009. Subsequent to the approval of the EIA
Report (EIAO Register Number AEIAR-146/2009), an
Environmental Permit (EP-354/2009) for TM-CLKL was granted by the Director of
Environmental Protection (DEP) on 4 November 2009, and EP variation
(VEP) (EP-354/2009/A) was issued on 8 December 2010. Subsequent
applications for variation of environmental permits (VEPs), EP-354/2009/B,
EP-354/2009/C and EP-354/2009/D, were granted
on 28 January 2014, 10 December 2014 and 13 March 2015, respectively.

Dolphin monitoring should
cover all transect lines in Northeast Lantau (NEL) and the Northwest Lantau
(NWL) survey areas twice per month throughout the entire construction period.
The monitoring data should be compatible with, and should
be made available for, long-term studies of small cetacean ecology in
Hong Kong. In order to provide a suitable long-term dataset for
comparison, identical methodology and line transects
employed in baseline dolphin monitoring was followed in the impact dolphin
monitoring.
The impact dolphin
monitoring was carried out in the NEL and NWL along
the line transect as depicted in Figure 2.3. The co-ordinates of all transect
lines are shown in Table 2.8 below.

The Action and Limit levels
of impact dolphin monitoring are shown in Appendix D. The
Event and Action plan is presented in Appendix K.
Dolphin monitoring was carried out on 8, 9, 14 and 29 of October 2019.
The dolphin monitoring schedule for the reporting
month is shown in Appendix
F.
One Chinese White Dolphins
sighting was recorded during the two sets of surveys
in October 2019. The dolphin sighting was made
in NWL, while none was sighted in NEL. The lone dolphin sighting was made during on-effort search and was made on primary
lines. The dolphin groups were not associated with any operating fishing
vessel.
No dolphin sighting was made in the proximity
of the TM-CLKL alignment. The distribution of dolphin sightings during the reporting month is shown in Figure 2.4.
Encounter rates of Chinese
White Dolphins are deduced from the survey effort and on-effort sighting data
made under favourable conditions (Beaufort 3 or
below) in October 2019 with the results present in Tables 2.9 and
2.10.

Note: Overall dolphin
encounter rates (sightings per 100 km of survey effort) from all four surveys are conducted in October 2019 on primary lines only
as well as both primary lines and secondary lines in Northeast and Northwest
Lantau.
Due to monthly variation in dolphin occurrence within
the survey area, it would be more appropriate to draw conclusion on whether any
unacceptable impacts on dolphins have been detected in relation to the
construction activities of this Contract in the quarterly EM&A reports,
where comparison on distribution, group size and encounter rates of dolphins
between the quarterly impact monitoring period and baseline monitoring period
will be made.
Daily marine mammal exclusion zone was in effect during the period of
silt curtain installation in open waters under this Contract. No sighting
of the Indo-Pacific humpback dolphin Sousa chinensis
(i.e. Chinese White Dolphin) was recorded in October
2019 during the exclusion zone monitoring.
Site inspections were carried out on a weekly basis to monitor the
implementation of proper environmental pollution control and mitigation
measures under the Contract. In the reporting month, five (5) site
inspections were carried out on 2, 9, 16, 23 and 30 October
2019.
Key observations and
recommendations during the site inspections in this reporting period are summarized in Table 2.11.
